Fuel shutoff. for or 20002 dodge stratus location emergency.


I just looked at a wiring diagram of the fuel controls for this model: there is no fuel shut-off switch in the wiring. It's pretty straight forward, typical fuel pump controls: the fuel pump relay is in the under-hood power distribution center. When this relay is turned on, power is sent to the fuel pump, nothing else is in the path of the hot wire to the pump module so it (the pump) should be working.

So if pump is not on, you can diagnose the wiring right here at the fuel pump relay. First you verify the power feed for the pump is available at the relay. (One terminal at the relay will have battery voltage with key off. If you pull the relay out and use a test light, one terminal position will be hot.) Next you verify the relay is working, sending power to the fuel pump in the gas tank. You do this by having someone cycle the key to on, while you hold a finger on the relay (it's back in place) to feel it click on. You should feel it, maybe even hear it, the relay will energize every time the key is turned to on, and this is what sends power to the fuel pump.` If it all works, and the pump is not on, the pump probably needs replacing. If the pump relay is not clicking on, that's a wiring hassle, including the wire to the engine computer. The pcm is what controls the relay turning on.
Do you know if the fuel pump has ever been replaced in the car? If it is original, it has been a good long run.

Where is the fuel pump fuse


Probably a relay, not a fuse. If there is a fuse it will be marked on the fuse box panel. Usually the relay is located under the hood either in a fuse/relay box or on a rack of several relay on the firewall.

No fuel pressure in efi system


Either the fuel pump is not working, or the filter is totally blocked.
The fuel pump circuit needs checked to see if it's a wiring problem or a failed fuel pump. There will be (probably) a fuel pump fuse in your fuse block, and a fuel pump relay under the hood.
If you check the fuel pump wire for power at the gas tank connector while the engine is cranking over, and there is power there, and the ground for the pump is good, then the pump is not working and will have to be replaced. If you do not have power when cranking, the wiring at the fuel pump relay will have to be checked. Simple relay- has a power feed for the pump at one relay terminal (it is hot at all times), and a fuel pump wire to pump on another terminal (the power out for relay). When relay coil side is energized from a signal from computer, the relay contacts close and power is sent to the pump. The other relay terminal is a ground for the coil side of relay. Pull the relay out and you will see the diagram etched on it. If there is a fifth terminal, that could be a pump prime terminal, or a way to keep the pump running when engine is running through the oil pressure switch. But when cranking the engine, the computer will signal the relay to send power to the pump.

2006 Ford Expedition blowing Fuel Pump Relay fuse


Try resetting fuel pump. I do believe the reset button is on the forward passengers side of vehicle. The button is behind the plastic shield. Reset once or twice. This hopefully will fix your problem. Look in your manual for exact placement of fuel pump reset button

Wont start think it might be fuel relay or pump


the relays are quite dependable now a days,check the fuse for the fuel pump in the fuse panel under the dash if the fuse is good then the relays are under the hood in a large relay box.you can interchange the relay with another relay that is the same as long as the relay is not used to run anything to allow the car to start.this will eliminate the relay.if the fuse is good you can just go from there to have someone bang on the fuel tank near were the fuel pump would be(middle of the gas tank),while someone tries to start the car,if it starts then it is the fuel pump that needs replacing and you won`t have to bother with the relay in the second step mentioned above.also the fuel filter could be plugged but you should hear the fuel pump working first.also just because you hear the fuel pump working it doesn`t mean that it is pumping at the correct fuel pressure

How does the feul pump relay works?


Hi and welcome to FixYa!
The fuel pump relay regulates the power given to the fuel pump. If the fuel pump relay is faulty there will be no power to the fuel pump and will result to fuel supply failure. These relays just like the others serves as regulators so that the battery will not fail during electrical loads.

Hope this helps and thank you for using FixYa! Have a good one!

How do i check the fuel pump relay and the fuel pump to see which is the bad part on a 99 Yukon 4x4, 4 door model?


The fuel pump relay should have a schematic on it so you can check it with an ohm meter for a short. If it checks ok and when you turn the key on, you do not hear the pump then replace the pump

Fuel won't pump to the carbarator


The fuel pump relay needs to be working to turn on the fuel pump. The fuel pump relay is behind the firewall of the battery. To confirm it is bad, pull off the relay and jump the wire at # 7 and #8 to energize the fuel pump. If it works then replace the relay. Good luck.

FUEL PUMP FOR CHEVY SILVERADO


fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?
